I just noticed that in the SM they say to adjusted idle current to -10mV +/-2mV (note the negative sign in front of the 10). I had adjusted the idle current to +10mV based on postings by the great Merrylander and others. Since I have nothing to lose I will try the -10mV setting and see what happens (and post results).
:twak:Since I have nothing to lose
No ,dont mess with it or you'll end up frying your outputs trying!!! ---- If you don't like the +10mv swap your test leads around. Absolute values!!! 10mv!!!!! Your actually adjusting the bias current ie milliamps that flow from the collector to the emitter of you output transistors at rest or idle.(quiescent) -- current is current +/- Macht Nichts !
Idle current (bias) has nothing to do with your popping. DC offset however might be and issue.
I can't believe you even made that statement with a 2040 :twak:
I'm not sure why the SM specifies "-10mV"?
I hooked up a separate amp to the Pre-Out jacks and I get the Pop through the external amp. Sounds like it isn't in the power amp section...
Any threads around with a Recap shopping list for a CR-2040?
Curious if you tried turning unit on/off with powerstrip and just leaving the on switch always on.
Just noticed the following comments in previous 2040 threads:
Just following up on this theory about new bulbs curing the power-off thump. I acquired a CR-2040 in nice shape except all the bulbs were out, and it made a LOUD pop/crack when the power was turned off, even with volume down. As suggested in this thread, replacing all the bulbs with the great dgwojo lamp kit fixed the pop! Did it fix your problem?
Comment by Merrylander
"The lamps are on the same supply as the protection relay and it is a filtered supply (in fact try using a diode to rectify AC and don't put a cap on its output, you will see some strange voltage). So without the load from the lamps to pull the power supply voltage to zero the protection relay has a tendency to hang up rather than do a fast release. This is why you get the pop on power off. "
All my bulbs are out, so I'm going to try hooking up some bulbs to test this theory.
Recap on hold...
